Useful whenever you declare a variable just for an `if` statement. That variable should be “inside” the statement but is at the same level.

Comes up regularly in my JS code. I loved having this feature when I wrote Go code—e.g. (stmt+expr!):

if match, _ := re.FindStringMatch(str); match != nil {…}

2/ Downsides:
A. More complicated file system structure
B. Two URLs for same file

I’m not sure but it must be.

Ah, wait! They are a multimap for servers because those receive both HttpOnly cookies and session cookies.

Query strings yes! But cookies?

> document.cookie = 'k=v1; k=v2'
> document.cookie
"k=v1"

They do make this feature less important than it once was but are complementary IMO:
• If a heading has an ID then a heading self-link goes to that ID.
• Otherwise, a text fragment link is used.

Even with text fragment links I still often use the heading self-links on GitHub, Wikipedia, my blog, …

Nice!

Example: GitHub adds a little paragraph “icon” to each heading that you can click in order to link to the heading. That is something browsers could do. I wrote a bookmarklet with that functionality and use it surprisingly often.

Three website features that could be built into browsers:
• Mode toggles (dark mode, light mode, print mode, …)
• Self-links for headings
• Cookie dialogs (with a default choice that can be triggered automatically)

I’m still making up my mind but I think I don’t want the font size to change depending on how large the viewport is.

Some insights:

• Helpful: “Please Don't Use JSON Web Tokens for Browser Sessions” by Ian London. ianlondon.github.io/posts/dont-u...

• By default, fetch() sends *and* receives cookies—which means you can use it to log in if session tokens are stored in HTTP-only cookies.
